Title: Short-circuit preventing circuit
Inventor: WHITTAKER EDWARD JOHN WEMYS
IPC: H02H7/20
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent excessive continuous current flow so as to protect an output transistor from damages by connecting the source of a third field effect transistor to the source of a first field effect transistor, and the gate of the third field effect transistor to the gate of the first field effect transistor. SOLUTION: To detect the current flow of a first transistor M1 , this circuit is provided with two transistors M2 and M3 , and the source of the transistor M2 is connected to the source of the first transistor M2 , and the gate of the transistor M2 is connected to the gate of the first transistor M1 and the signal source of a signal supplied to a load. Then, the gate of the transistor M3 is connected between the both ends of the transistors M1 and M2 , so as to be connected to the gate of the second transistor M4 . This current flow which passes the transistor M1 produces voltage drop, and pulls up the diode made of the transistor M4 . As a result of this, an output buffer where the short circuit is prevented, can be provided without the necessity of a series detection element.

Title: Linear approximation system
IPC: G09G5/24
Filed: 1992-03-19
Abstract: PURPOSE:To greatly shorten the processing time required for linear approximation by finding the farthest point which has the largest difference from each point of a point sequence to a straight line in a specific coordinate direction, and then calculating only the distance of the farthest point and performing the linear approximation so that the distance is less than a permissible value. CONSTITUTION:This system is equipped with a farthest point extracting process part 2 which extracts the farthest point having the largest difference among differences from the respective points between the start point and end point of the point sequence to the straight line connecting the start and end points in the specific coordinate direction and an actual length calculating process part 4 which calculates the distance between the farthest point and straight point; when the distance calculated by this actual distance calculating process part 4 is less than the permissible value, the approximation is performed by using the straight line connecting the start and end points, but when the distance is larger than the permissible value, on the other hand, the process is repeated by using the farthest point as an end point.

Title: Processor fitted with gate valve
Inventor: YAMADA KEIJI
IPC: F16K51/00
Filed: 1990-03-15
Abstract: PURPOSE:To directly discharge dust produced during operation of a valve, so that it may not adhere to a product and that the defects or inferiorities of products may be reduced thereby by providing a mechanism, which concentratedly discharges air in the vicinity of the gate valve when the gate valve for opening or closing plural processing chambers is operating to open or close them. CONSTITUTION:The wafers 6 to be processed are sent one by one in order into each processing chamber continuously. First, the wafer 6 is sent from outside a device into the processing chamber 9 by opening the valve 7 inside a gate valve body 8. At that time, the valve 7 descends by a valve driving valve 12, and at the same time when the interval between the device outside and the processing chamber 9 opens, a valve 14 for opening or closing a discharge circuit opens, interlocking with it, and air discharging is performed from the discharge pipes 13 in front and in rear, and the dust produced by the friction of the valve 7 is discharged from the discharge pipe 13. Next, when the wafer 6 is sent in the processing chamber 9, and the valve 7 ascends, and interrupts the processing chamber 9 from the outside, the valve 14 for opening or closing the discharge circuit opens as before, and discharges the reproduced dust to the outside of the device.

Title: Spiked tire with cylinder
Inventor: HORIUCHI TAKASHI
IPC: B60C11/16
Filed: 1982-04-19
Abstract: PURPOSE:To prevent a road surface and a spike from wearing, by a method wherein a large number of single-acting cylinders provided with a spring for taking in and out of the spike is provided within a tubeless tire and hydraulic oil is fed and discharged by a manual pump from the outside of a wheel so that the spike is made to take in and out. CONSTITUTION:When hydraulic oil is fed by a manual piston pump not illustrated through a check valve 17, the hydraulic oil is fed into each cylinder 1 through a hydraulic hose inside a tire 5. At this time, air breathing at the time of lubrication is done by turning an air-bleeder plug 16 into an open state. In this way, a piston 9 of the cylinder 1 actuates a spike 6 to protrude from the surface of a tire 1. If hydraulic oil is made to discharge through a hydraulic oil discharge opening 15 provided on a wheel 13, a titled tire becomes a conventional one by retiring the spike 6 by force of a spring 10. Thus a road and the spike are prevented from wearing as the spike is made to protrude only when it is necessary.
